VOLTAIC BODY-BATTERY.

Application filed August 4, 1913.

To all whom it may concern Be it known that I, AUSTIN A. PRATT, acitizen of the United States, residing at Los Angeles, in the county ofLos Angeles and State of California, have invented a new and usefulVoltaic Body-Battery, of which the following is a specification.

The present invention relates to improvements in a voltaic body battery,one object of the invention being the provision of a compact battery ofthis character, employing a number of different metals, wherebydifferent actions take place when the battery is applied to the humanbody, the various metals being properly supported upon a body or disk ofinsulation and being preferably composed or formed in the shape of acircular disk.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed without departing from the spirit of the in'vention.

In the drawings-Figure 1 is a front elevation of the complete battery.Fig. 2 is a rear elevation thereof. Fig. 3 is a section taken on line3-3 of Fig. 1.

Referring to the drawings, the numeral 1 designates a circular disk ofinsulation material, preferably hard rubber or guttapercha, the samehaving formed upon one face thereof, the two circumferential recesses 2and 3, and the central aperture 4. A plurality of equally spacedapertures 5 are formed through the body of the disk.

Seated within the annular recess or depression 2 is a ring 6 composed ofa zinc composition, said ring being held properly in place by means ofthe copper eyelets 7 which are disposed through the openings 5 and arebeaded upon their respective outer ends so as to maintain the zinccomposition ring 6 in place. Two rings 8 and 9 are disposed within therecess 3 of the disk 1, the larger or outer ring 8 being composed ofsilver while the inner ring is composed Specification of Letters Patent.

of copper, the aperture 4 of the disk being filled with a plug or button10, which is composed of zinc composition and is provided with thepocket or socket 11 upon the face adjacent to the recessed portion ofthe disk 1 for the reception of the button 12 of gold.

The present battery is to be used in a similar manner to other voltaicbody batteries, it being the purpose of the present invention to carryin the insulation disk four different metals, as set forth. Thus, thesedifferent metals are so constructed and arranged as to produce thedesired number and different currents of electricity when the presentdevice is applied to the flesh of a person.

By incasing the metals in a disk of insulation as herein set forth, suchinsulation being of such a material as to permit of the washing andsterilizing of the battery, it is evident that a durable and sanitarydevice of this character is provided.

\Vhat is claimed is:

1. A voltaic body battery, including a disk of insulation having acentral aperture and a plurality of concentric recesses in one facethereof, a ring of zinc composition disposed in the outer recess, a zincbutton disposed in the central aperture, and a plurality of rings ofdifferent metals disposed in the inner recess of the disk and about theinner zinc composition.

2. A voltaic body battery, including a disk of insulation. having acentral aperture and a plurality of concentric recesses in one facethereof, a ring of zinc composition disposed in the outer recess, a zincbutton disposed in the central aperture, a plurality of rings ofdifferent metals disposed in the inner recess of the disk and about theinner zinc composition, said zinc button having a concentric socket inthe face adjacent the metal rings, and a filling of a dense metal insaid socket.

In testimony that I claim the foregoing as my own, I have hereto afiiXedmy signature in the presence of two witnesses.
